Tools to Track down Your Server
The very good information is you do not require a super accurate check, rather, a comparatively accurate option is easily accessible. All you require is a little being familiar with of the pace of light and optical fiber! Essential items of info:
1. Gentle travels at around 186,000 miles per next or 186 miles per millisecond in a vacuum.
two. Fiber has a refractive index of all around 1.46.
3. The modern-day “Internet” is fiber when working with extended distances.
In circumstance you have not recognized, these are not actual calculations.
The subsequent step in your mastering procedure is to comprehend a “ping” check. You likely have the “ping” tool on your computer already. “Ping” is a simple application utilized to examine community connectivity and general performance. It will deliver a check packet of info out to a specified domain or IP and time how extended it usually takes for that domain or IP to answer. It will report that back again to you in “milliseconds.” We have instructions if you have in no way utilized this in advance of.
After you have completed the ping tests, just get the the resultant milliseconds and multiply it by the pace of light in fiber. This will give you the spherical journey mileage. Divide by two for the 1 way distance:
Taken from the typical end result of the Linux case in point from over for a ping from Newark, Delaware to Los Angeles, California
77.two Milliseconds * 186 miles per millisecond / 1.46 refractive index = 9835 miles spherical journey or 4918 1 way.
Wait a millisecond, touring from Newark, DE to Los Angeles, CA is not nearly 5000 miles! Straight line distance is about two,350 miles. The shortest distance by car or truck from Google is 2700 miles. In this circumstance, mainly because we have a very good concept of what cities the physical route goes by means of, it is about 3,two hundred miles. So what presents?
There are a bunch of exterior things that affect the “distance”:
1. The check packet have to be encoded and decoded by your computer and the goal computer.
two. Devices like switches and routers (try out a “trace route“) have to interact with your packet to get it to it’s place.
3. Not all of the route will be about fiber. Most of it will be, but sure parts this sort of as your possess Internet connection, will not be.
4. Life is not ideal.
Check out It Oneself
Having said that, this is a good way to look at “distances” to find your server area. Check out it out on distinct web pages and look at it to to our East Coast data center (suburban Washington, D.C.) and our West Coast data center (Los Angeles, California). Ping the pursuing to see the variance:
